Series applied to dpdk-next-net-mrvl/for-next-net with following chages. Thanks.

1) cnxl ml driver update in doc/guides/rel_notes/release_23_11.rst
moved to close to mldev subsystem changes

For the record, I have used following build command to test code with
external build dep.

Assumung all depended libraries installed at /export/cross_ml/install/

CMAKE_PREFIX_PATH='/export/cross_ml/install/lib/cmake/tvm:/export/cross_ml/install/lib/cmake/dlpack:/export/cross_ml/install/lib/cmake/dmlc'

Also, -Dc_args='-I/export/cross_ml/install/include'
-Dc_link_args='-L/export/cross_ml/install/lib' could be removed when
